I just removed the dates on a
Kennedy half dollar page and I must say I'm happy how it came out. I used acetone and a q-tip lightly rubbed until the ink started to smear then used hand sanitizer with a new q-tip. A bit of the "gloss" was reduced but I think that is because I became impatience as I progressed onto the next date.
Good thing is you can practice/experiment on the printing that is on the left side of page and hidden when enclosed in album
2nd photo I tried to show the reduced "gloss"
